ʻO ka uea Manganin he copper-manganese-nickel alloy (CuMnNi alloy) no ka hoʻohana ʻana i ka wela lumi. Hōʻike ʻia ka alloy e ka ikaika electromotive thermal haʻahaʻa (emf) i hoʻohālikelike ʻia me ke keleawe.
Hoʻohana maʻamau ka uea Manganin no ka hana ʻana onā kūlana kū'ē, nā mea pale uea pololei, potentiometers, shunts a me nā mea uila a me nā mea uila.

Nā kikoʻī
uea manganin/CuMn12Ni2 Uea hoʻohana ʻia i nā rheostats, nā mea pale, shunt etc.
ʻO ka uea Manganin (ʻo ka uea cupro-manganese) he inoa inoa inoa no ka huila o 86% keleawe, 12% manganese, a me 2-5% nickel.
Hoʻohana ʻia ka uea Manganin a me ka foil i ka hana ʻana i ka resistor, ʻoi aku ka ammeter shunts, no ka mea, ʻoi aku ka nui o ka mahana o ka waiwai resintance a me ke kūpaʻa lōʻihi.

Ka hoohana ana o Manganin

Hoʻohana ʻia ʻo Manganin foil a me ka uea i ka hana ʻana i ka resistor, ʻoi aku ka nui o ka ammeter shunt, no ka mea, ʻaʻole kokoke loa i ka helu ʻana o ka waiwai kūʻē a me ke kūpaʻa lōʻihi.
Hoʻohana nui ʻia ka mea keleawe haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, thermal overload relay, a me nā huahana uila haʻahaʻa haʻahaʻa. ʻO ia kekahi o nā mea nui o nā huahana uila haʻahaʻa haʻahaʻa. ʻO nā mea i hanaʻia e kā mākou hui he mau hiʻohiʻona o ke kūpaʻa kūpaʻa maikaʻi a me ke kūpaʻa kiʻekiʻe.
